6 Claims. 1

This invention relates to a switch construction and is particularlydirected to a high voltage switch such as a disconnecting switch forinstance, although the invention is not limited to this type of switch.

Objects of this invention are to provide a construction which isapplicable either to a single switch or to a gang type switch, in whicha mu]- tiplicity of switch blades or switch members are provided and areadapted for simultaneous actuation.

Further objects are to provide a switch construction in which the partsare carried by insulator stacks, and in Which the construction is suchthat the insulator stacks are not strained by stresses tending to drawthem together or forcethem apart, in which the switch arm may be as longas desired and may be constructed of tubular stock, whereby its weightmay be reduced, or, if desired, may be constructed from rod or otherstock material, in which a high contact pressure is secured between thestationary contact means and the movable contact means when the switchis closed, in which this high pressure is relieved prior to opening ofthe switch, and in which the component parts of the arcing horns arekept out of contact when the switch is closed, thereby lessening thechance of the arcing horns freezing tight under sleet conditions, and inwhich a certain portion of the arcing horn construction is moved intocontact with the remaining portion of the arcing horn constructionduring opening motion of the switch.

Further objects are to provide a switch having a pivoted switch armconstruction, certain forms of the invention being provided withresilient switch arms and with mechanism which not only secures highcontact pressure between the movable and stationary contacts, but alssecures high contact pressure at the pivoted portions of the switch,thereby avoiding the necessity of using a flexible leader when flexibleswitch aims are used, the invention, however, permitting the use ofrigid switch arms and a flexible jumper or leader at the pivoted end ofthe switch when rigid switch arms are used.

Further objects are to provide a switch construction in whichcylindrical switch members preferably of tubular form are employed andin which a high contact pressure on a stationary contact is obtained atopposed points on the stationary contact so that the pressures arebalanced and no external stresses are imparted to any other portions ofthe mechanism.

In greater detail, objects of this invention are 2 to provide tubularmain switch members which grip between them a cylindrical stationarycontact member, thereby obtaining small area, high pressure contactingportions, the movable contacts extending transversely across thestationary contact when the switch is closed.

Further objects are to provide a construction in which it is notnecessary to employ any latches to insure the correct sequence ofoperation of the parts, but in which very simple mechanisms are providedfor insuring the correct sequence of operations of the switch parts, andin which in certain forms of the invention the inherent resiliency ofthe switch arms is utilized and in another form of the invention inwhich relatively rigid switch arms are used while still obtaining thedesired heavy contact pressure between the stationary and movablecontacts and the correct se- I quence of operations.

Further objects are to provide a construction in which the switch armportion is so made that it is laterally braced, in which the partscooperate to insure correct centering or positioning of the movablecontacts when the switch arm is rocked to closed position and to providea construction which is very simple, which is highly reliable inoperation, and which is economical to manufacture. v

exaggerated showing the lines of flexure of the switch arms.

Figure 17 is a sectional view showing a gang switch, such sectioncorresponding to'a sectionon the line l1l1 of Figure 1.

Referring to Figures 1 to 8, it will be seen that the switch comprises abase I which supports three stacks of insulators indicated by thereference characters 2 3 and 4.- The stack 4 is revolubly mounted and isrotated bymea'ns of a shaft 5- or in any other suitable manner; Theswitch is shownas a singleswitch but, as will appear hereinafter, it isthe usual practice to mount aplurality of switches and operate: them asa gang switch.

The insulator 2 carries a stationary contact which-may be in the formofan upstanding cylindrical pin 6 which has a tapered upper portion 1and a pair of outwardly projecting stop pins 8 to arrest the downwardmotion of the movable con.- tacts of the switch as will appearhereinafter. The pin 6 is rigidly mounted on a terminal 9' and theterminal carries a pair of flaringv arc horns Ill. The insulator stack3' rigidly carries a terminal I I'. The terminal H isalso supported fromthe insulator stack 4, such stack having an upper member l2 providedwith an upstanding portion l3; which.isrevoluble-within the terminal Il, the terminal. I I" thereby forming a brace between the insularstacks- 3 and 4.

A. pair of pivot. supports l-4- are rigid with the terminal H and. are.supported from the. insulator stack 3. These pivot supports carry thpivot pin I5 about which the switch arms [6. rock when the switch isopened and closed. Theinner faces of the pivot support means constitute.contact faces as will. hereinafter appear.

The switch arms 16 are. tubular and are preferably formed of copper orother good conducting material. They may be flattened at their. pivotedends or may, as shown in the drawings, be provided. with end portions I!which are directly pivoted. on the-pin 15. An idler link I8. ispivotally mounted on. the pin and is pivoted to a con.- necting link l9by means of a pivot pin 20, the link. l9' being operatively connectedtov the switch arms l6 for raising and lowering the switch arms as willhereinafter appear. An intermediate link 21 is also pivoted on the pinand is pivoted to the connecting link 22 by means of a pivot pin 23. Itis to be noted that the pivot pins 20' and 23 are at right angles toeach other and that the con struction thus provides a universal joint.

An operating crank 24 forms a rigid part-,- of the upper member 12 ofthe insulator stack 4 and is provided with a crank pin 25 which carriesan intermediate link 26. The intermediate link 26 is pivoted to theconnecting rod 22 by means of the pivot pin 21, it beingnoted that thepivot pin 21 is at right angles to the crank pin 25 and the constructionthus forms a universal joint. It is apparent, therefore, thatwhen .6insu o stack 4 is rotated in a clockwise direction as viewed in Figure2, the switch arms will be raised to the dotted line position shown inFigure 1. It is to be noted from Figure 1 that a pair of stops 28 arerigidly supported from the insulator stack 3 and provide means forarresting the switch arms in a slightly over center position when theyare fully raised.

The switch arms 16 are resilient and this resiliency is utilized insecuring a binding engagement or heavy contact pressure between theouter ends. of the switch arms I6 and the stationary contact or pin 6and also in securing a heavy contact pressur between the pivoted endportions ['1 of the switch arms and the ears or pivot supports 14. Apair of members 29 are rigidly secured: to the switch arms at a pointspaced inwardly from their outer ends and are pivotally joined by meansof the pin 33. These members 29 constitute tie members and .tie theswitch arms together at: this point. These tie members, therefore,.constitutev means for maintaining substantially"constant spacing of thearms at a point spaced inwardly from their outer ends. In addition tothis, these tie members constitute means for preventing. relativelongitudinal motiorr. of the arms; It is also to be noted that the mainpivot ['5 also prevents relative longitudinal shifting of the arms Inaddition to this, the pivot and the tiemeans' coacting with the armsproduces a laterally braced truss like structure.

The arms are. also provided with a pair of socket; members 3| which are.rigidly attached thereto at points spaced outwardly from the inner orpivot ends of the switch arms 15. These socket members are shown in.greater detail in Figures 5,6 and 7.. The are:- each provided withinwardly directed sockets 32' which have rounded inner ends The link 13is bifurcated at its outer end: and carries a pivot pin 33? upon: whichare pivoted a pair of members 34" and 35 the member. 34 beingbifurcated: and. receiving. the member 35 between: its two arms; asshown: most clearly in. Figure: 72. The members 34 and 35 arerespectively provided with outwardly projecting toggle members: 36* and31' which: have rounded outer ends-seating; within the sockets 32'. Themembers 34' and 35 also have stop projections 38 and 39 respectivelywhich when the toggle mechanism is. in its final expanded positionasshown in Figure- 5- are: spaced apart, but which are. arranged tocontact when thetoggle isin its most collapsed position as shown inFigure. 6;.

It is to benoted: that when". the toggle mechanism is: in its; mostcollapsed position as shown inFigures 31 and 6, the outer ends of' theswitch arms 16 do not have a heavy pressure engagement with thestationary contact 6; However, when the toggle link mechanism is in. itsexpanded position as shown in Figures. ZJand 5, the arms 55 are forcedapart at the members. 3! and in view of. the fact. that they are pivotedat 33, it will be seen that their outer ends engage the stationarycontact 6 witha very heavy contact pressure. Also it will be; seenthatthe members l1 are forced apart into. heavy binding engagement with thepivot supports. or ears I 4.

It is tobe noted: from. reference to Figures 5 and: 6 thatthe'outersides of the sockets 32', that is to say, the walls of the. socketslocated towards the free end. of the. switch arms, are less steep thanthe rear walls of the sockets 32. This construction allows the togglemembers 36 and 37 to be rocked slightly past dead. center when theswitch is closed, as shown in Figures 2 and 5, to thus lock the switchin closed position with heavy binding pressure at the contacts. However,when the toggle is collapsed the rear walls of the sockets 32 aresuiiiciently angularly disposed to allow the toggle to collapse to aconsiderable extent to the position shown in Figure 6, thus allowing themembers 3| to move inwardly and allowing the switch arms Hi tostraighten themselves out due to their inherent resiliency.

It is to be noted from Figures 2 and 3 that the members 29 carry themovable elements 40 of the arcing horns. When the toggle mechanism is inits most expanded position, it will be seen that the movable arcinghorns 45 are out of engagement with the stationary arcing horns Hi. Thisis particularly desirable as under sleet conditions it prevents thearcing horns from freezing together. However, when it is desired to openthe switch, the crank 24 is rocked in a clockwise direction and thefirst effect is to collapse the toggle mechanism and allow the switcharms |5 to straighten out to the position shown in Figure 3. When thisoccurs, the movable arcing horns 45 move outwardly into engagement withthe stationary arcing horns l5 and this occurs prior to any raisingmotion of the switch arms I5. When the switch arms it straighten out,the heavy contact pressure against such pin is relieved and also theheavy contact pressure at the pivoted ends of the switch arms isrelieved. It is thus a relatively easy matter to raise the switch byrotating the crank 24 in a clockwise direction.

When the switch is being lowered to close position, there is no chanceof the parts jamming or operating in the wrong sequence. The weight ofthe switch arms pulls downwardly against the connecting link is and thuskeeps the toggle mechanism in its most collapsed condition. As theswitch is lowered, the arcing horns 40 first engage the outwardlyflaring arcing horns ill and serve to roughl guide the switch arms l5into position on opposite sides of the stationary contact 5. They areadditionally accurately guided into position by the tapered upper end 1of the stationary contact 6, see Figure l. The switch arms continue todescend until they rest upon the stop pins 8. Thereafter continuedmotion of the crank 24 in a counterclockwise direction as viewed inFigure 2 causes the toggle mechanism to expand and causes heav contactpressure between the switch arms and the stationary contact 5 and alsoheavy contact pressure at the pivoted ends of the switch arms.

The diagrammatic view of Figure 15 shows in a very exaggerated mannerthe deflection of the switch arms I6 when the toggle link mechanism isfully expanded. The forces indicated by the arrows at F are directedoutwardly and it. will be seen that the switch arms 5 bow outwardlybetween the pivoted inner ends and the members 29 with the radius ofcurvature located inwardl of the arms. However, past the members 29 theswitch arms bow in the reverse direction, that is to say, with thecenter of curvature on the outer side of the switch arms.

The toggle members 35 and Si and the members 3| are made suificientlyheavy or strong so that the weight of the switch arms i5 when they areraised and lowered will be easily carried by such members while the linkI9 raises or lowers the switch arms.

Referring to Figures 9 to 12 which show a further form of the invention,it is to be noted that the switch arms |5 are as previously describedand are provided with the end members I! pivoted on the pivot pin I5 andsupported by the pivot supports M. The idler link I8 is pivotallyconnected to intermediate links 4| by means of the pivot pin 42. Theouter end of the links 4| are pivoted by means of the pivot pin 43 tothe upstanding arm 44 of a cam member indicated genorally at 45. The cammember is pivotally mounted on a pivot pin 46 which is slidable andloosely received within socket members 41, see Figure 12, rigidlycarried by the resilient switch arms IS. The cam member 45 is providedwith upwardly and outwardly flaring or tapered portions 48 which areadapted to force the switch arms l5 apart when the cam member 45 isrocked downwardly to the position shown in Figures 9 and 11. It ispreferable to provide flat portions or parallel portions 49 at the upperportion of the cam surface so as to tend to lock the switch arms IS intheir outwardly pressed position as shown in Figures 9 and 11. The cammember 45 is provided with upper and lower stops or outwardly projectingportions 59 and 5| respectively. When the switch is opened, it isapparent that when the crank I2 is rotating, link 22 will be drawn tothe left as viewed in Figures 9 and 10 and will draw the links 4| to theleft and thus rock the cam member 45 in a counterclockwise direction.The cam will continue to move upwardly, thus allowing the switch arms IEto resume their original straight shape until the lower stops 5| of thecam member 45, see Figure 11, come into engagement with the switch armsI5. The switch arms are now fully collapsed and are lifted by the cammember upon continued operation of the crank.

There is no chance of jamming when the switch is being closed as thereis no danger of the sequence of operations hereinbefore describedoccurring out of order as the weight of the switch arms holds the switcharms downwardly with reference to the cam 45 until the switch arms arebrought to rest at the stationary contact. Thereafter further operationof the main crank rocks.

the cam member 45 downwardly to the position shown in Figures 9 and 11,thus locking the switch closed with heavy contact pressure both at thestationary contact and at the pivoted ends of the switch arms.

In the forms of th invention heretofore described resilient switch armshave been employed. However, it is possible to employ rigid switch armsand one form of the invention in which rigid switch arms are employed isillustrated in Figures 13, 14 and 15. These rigid switch arms areindicated at l6 and are provided with pivoted end portions l1 pivoted onthe pivot pin |5 as hereinbefore described. The inner or pivoted ends ofthe rigid switch arms I6 are biased in wardly towards each other bymeans of the spring 52. Means are provided for forcing the inner ends ofthe switch arms l6 outwardly in opposition to the action of the sprin52. This causes the switch arms IE to pivot about the outer pivot pin 30hereinbefore described, see Figure 2, and causes the front or outer endsof the switch arms to bind against the stationary contact with heavycontact pressure.

It is preferable to leave a clearance between the pivoted portions I1and the ears M and to provide a flexible jumper or connector 53, seeFigure 13, between the cam member 54 and the terminal II. The cam member54 is pivoted on the main pivot pin I 5 and is provided with a pair ofintegral arms 55 which are shaped somewhat like the connecting link |8of the first forms of the invention. The arms 55 of the cam member:carry a pivot pin 56 which .pivota'lly supports the connecting link 51,the connecting link 51 being in turn pivoted to the connecting rod 22 inthe manner hereinbefore described.

It is obvious from the description thus far given that when theconnecting rod 22 is drawn to the left as viewed in Figures 13 and 14,the cam will 'be rocked upwardly and when driven to the right, the camwill be pressed downwardly.

The cam 54 is shown in detail in Figure 15 and it will be seen that ithas upwardly and outwardly slanting cam faces 58 and flat or parallelfaces :59 at the upper ends of the cam faces. The cam is adapted'tocooperate with the pivoted portions ll of the switch arms 16. It isprovided with upperand lower stops 6B and BI.

It is obvious that when the switch is closed and the connecting rod 22is driven further to the right through operation of the crankhereinbefore described, the inner or pivoted ends of the switch armswill be spread apart and the outer ends of these rigid switch arms willtightly grip the stationary contact, thus providing high contactpressure. When the switch is to be opened, the crank is rotated to drawthe connecting rod 22 to the left as viewed in Figures 13 and 14 and thecam 54 is rocked upwardly from the position shown in Figures 13 and 15.This allows the spring 52 to draw the pivoted ends of the switch arms ISinwardly and thus relieve the heavy contact pressure at the stationarycontact.

In the forms of the invention shOWn in Figures 9 to '12 and in Figures13 to 15 it is intended that the outer ends of the switch arms be tiedtogether in the same manner as described for the first form of theinvention.

In all forms of the invention, when the switch is closed but before theswitch arms are deflected by the deflecting mechanism, it is optionalwhether or not the outer portions of the switch arms I6 will have alight contact pressure on the stationar contact 6. It is, however,preferable to have no contact pressure so that, with even a slightcoating of ice, there will be no resistance offered the switch armswhich might cause the deflecting mechanism to operate and thereby causethe blades to assume their deflected position. When the switch arms aredeflected, there is a slight relative motion between the outer portionsof the switch arms and the stationary contact 6 sufficient to scrape offany scale or oxide that may have formed.

In all forms of the invention the movable arcing horns are out ofcontact with the stationary arcing horns when there is heavy contactpressure and are in contact with the stationary arcing horns when thisheavy contact pressure is relieved.

In all forms of the invention the pivoted ends of the switch arms have arelatively loose fit with the pivot pin to allow them to freely slide onthe pivot pin during operation of the switch.

The switches in all forms of the invention are usually mounted as gangswitches, that is to say, 'a plurality of switch units are employed asshown in Figure 1'7. In this case the shafts are provided with rock arms62 rigid therewith which are connected by means of a series ofconnecting links 63 and 64. One of the rock arms is connected by meansof connecting link 65 with a master crank 68 carried by the rock shaft6? and adapted to rock through at least 180 so as to lock the switchesboth in closed and in open positions. If desired, the master crank arm66 could swing slightly past dead center .at each end of its stroke toinsure locking.

It is to be understood that the switch arms '16 or I B may be made aslong as desired depending on the voltage of the circuit in which theswitches are to be used. They are ordinarily used in the well knownmanner as disconnecting switches.

It is to be noted that the switch arm is or 'IE are not mounted oneabove the other, as has often been done in the prior practice, but aremounted opposite each other in the same plane. It is also to be notedthat toggle link mechanism or cam mechanisms are employed to expand theswitch arms laterally, that is to say, in a horizontal plane, in orderto get the high contact pressure. Decided advantages result from thisarrangement in that the switch arms form a laterally braced movablestructure and also particularly in that no catches are required toinsure the correct sequence of operations of the parts. Instead theweight of the switch arms coacting with the toggle link mechanism orwith the cam mechanism forcibly holds the switch arms in their relaxedcondition and precludes the possibility of the switch arms being movedto their clamping or high pressure position until after the switch armshave been brought to rest in engagement with the stationary contact.

It will be seen further that at the stationary contact and the free endof the switch arms a small area high pressure contact is obtainedandalso in at least the first two forms of the invention a heavy contactpressure is obtained at the pivoted ends of the switcharms. It ispreferable, as previously described, to depend upon a flexible leaderfor the electrical connection at the pivoted ends of that form of theinvention having the rigid switch arms.

It will be seen that the mechanism of the switches is very simple andthat the parts may be made sturdy and that the switches will be reliablein operation.

In all forms of the invention the correct .sequence of operations is notdependent on any latches, catches, or other devices of this nature and,at least in the first two forms of the invention, is not dependent uponthe action of any springs whatsoever as the Weight of the switch armswhile the switch is being raised or lowered always holds the toggle orcam members in a position so that the switch arms are relaxed.

Although this invention has been described in considerable detail, it isto be understood that such description is intended as illustrativerather than limiting, as the invention may be variously embodied and isto be interpreted as claimed.
